1. My present invention involves improvements in the art of book-binding. I

2 Claims (Cl. 281-21) My primary objects in developing my invention have been to devise a novel tab connecting means between the leaves or pages of the book enabling the fiat opening of the latter atany page thereof, obtaining the full benefit of the entire sheet for carrying printed matter or as a writing surface, eliminating the need for spiral or ring binding which only affords weak connections between the leaves and the leaves with the binder, and which permits of rapid and easy assembling and attachment of the leaves together.

A further object of my invention has been to devise peculiar tab connecting parts between and integral with the leaves or pages, which not only afford the fiat opening function above mentioned, but are so formed, and '50 disposed in relation to the leaves thatthey do not any way increase the thickness, or cause bulking, of the bound together portions of said leaves.

Still another objective achieved by my invention lies in the provision of attaching means between the leaves of the book conducive to enabling the employment of pressure and heat only for effecting the final binding operation, to which end I apply to the tab attaching parts an adhesive which is hard or non-sticky at normal temperature and becomes effectively adherent on the application of predetermined sufficient heat.

According to my invention the peculiar tab connectors that I employ between certain leaves or sheets of the book are struck from the body of the leaf adjacent to the binding edge, but their formation does not weaken the sheet for binding purposes to any material extent. Moreover, by adhesive connection between the tab of one leaf, and an adjacent leaf, peculiar to my invention, when the leaves are together with the book closed, the tabs of a leaf simply occupy the space of this leaf from which they are struck out notwithstanding that they are adhered to an adjacent leaf. By this method the bulking of the leaves at their bound portions, previously referred to, is avoided, because the thickness of the adhesive used on the tabs is negli ible and does not create bulking in any tangible degree.

Another advantage of the book leaves assembly hereof lies in the fact that the same will prove especially effective for account books, bank passbooks, installment payment books and the like, since if a sheet of my book is removed an associated sheet will be detached or fall out, leaving clear indication of tampering, something not '2 true as regards the customarily used books of the above class.

Another feature of my novel book binding invention and method of carrying out the same resides in so constructing the leaves that the tab parts may be struck out'or cut, and adhesive simultaneously applied thereto, leaving only the folding, stacking, compressingand heating operations to be performed, and the latter can be accomplished as quickly as the cheapest present day binding of scratch pads, or thelike, is effected.

My invention may take different forms but in the following detailed description, to' be read in conjunction with the annexed drawings, I have set forth several preferred forms only.

In the accompanying drawings:

Figure 1 is a plan View of a series of leaves or leaf units of my invention as when superposed upon one another, the units being folded so that when folded they lie one unit within the other as distinguished from the construction of my invention of Figures 1 and 2 primarily wherein the U-folded leaf members or units are disposed side by side.

Figure 2 is a longitudinal sectional view through the arrangement of assembled leaves as shown in Figure l the section being taken on any one of the lines 2-2 indicated in Figure 1, since the tab arrangements at these portions of the assembled leaf units are the same.

Figure 31s a sectional view similar to that of Figure 2 but taken on the lines 3-3 of Figure 1 at which points of section the tab arrangements are different or reversed from those illustrated in Figure 2 as later to be specifically described.

Figure 4 is a sectional view somewhat similar to Figure 2 taken on the same lines as Figure 2 but illustrating the leaf units or respective folded leaves as when they are bent somewhat at their hinged portions, the illustration bringing out more clearly the manner in which a tab member or members of one leaf unit of U-form is connected adhesively to a solid uncut leaf of anadjacent or juxtaposed leaf unit.

Figure 5 is a view similar to Figure 4 taken on the lines 3-3 of Figure 1.

Figure 6 is a perspective view of a book of assembled leaf units or leaves like those as arranged in Figures 1 to 5 inclusive, the lower portion of the leaves of the uppermost leaf unit being broken away in order to show the arrangement of the tab means of the next lower leaf unit.

Figure 7 is a view similar to Figure 6 but showing a further modification of my invention in which the tab members for the various leaf units extend all in the same direction as distinguished from Figure 6 wherein the tabs of adjacent leaf units extend in opposite directions.

Figure 8 is a view similar to Figure 1 showing the modified structure of Figure 7.

Figure 9 is a view similar to Figure 2 but the section is taken on the lines 9-9 of Figure 8.

Figure 10 is a sectional view taken about on the lines Ill-l of Figure 8.

Figure 11 is a fragmentary view much exaggerated in size to bring out more clearly the tab features and their arrangements according to the construction of Figures 7 to 9 inclusive, the view being a sectional view somewhat 'analagous to those of Figures 4 and 5.

Concisely describing now the several modified constructions of my invention indicated herein merely as preferred adaptations of the invention I refer first to Figures 1; to inclusive.

I refer to Figures 1 to 5 inclusive of my drawings which illustrate my invention in which the leaf units are made up of U-folded leaves or sheets to provide the leaves side by side. According to the construction of Figures 1 to 5 these leaf units are interleaved together or in other words when the U-folded unit is laid out fiat it is disposed fiat against the other under juxtaposed leaf units and they are simultaneously bent at their fold lines inmaking the bound portion of the book that is attached to the cover at the back thereof in the customary way.

Referring particularly to Figures 1 to 5 inclusive in which no cover is illustrated for the purposes of my invention, it will be seen that the leaf units are designated 9, III, II and I2 from the uppermost to the bottom unit shown. I indicate the hinge line for the leaf unit at l3. According to this construction now being described the top leaf unit 9 has the tabs thereof, designated l4 struck out from the right hand leaf of the unit adjacent to the fold or bend line IS. The undersides of these tabs [4 therefore extend in an overlapping arrangement upon the next lower leaf member, the right one of the leaf unit It, and are adhesively attached thereto by adhesive l5.

According to the modification now described the upper leaf unit 9, to be ultimately a folded leaf unit comprising two leaves of pages, has

four tabs 14 struck or cut therefrom to connect the same with the next lower leaf unit IB. In like manner the third lower leaf unit II has a series of tabs I 4 struck therefrom which are connected adhesively to the lowermost leaf unit l2 after a manner similar to the connection of the tabs between the parts 9 and 10.

Now as respects the second lower leaf unit If! of the group shown in Figures 2 and 3 it is noted that this unit has the tabs [6 cut therefrom which tabs however are arranged on the opposite side of the fold or hinge line l3 from the side at which the tabs H! are disposed as previously described. The fourth lower or bottom leaf unit !2 is provided likewise as seen in Figure 3 with tabs 16 that are cut out therefrom to the left of the hinge line l3 as contrasted with the arrangement of the tabs 14 previously described. The tabs I6 have adhesive IS on their lower sides for adhesive connection to the next lower leaf unit.

Figure 6 shows somewhat more clearly as well as Figures 4 and 5 just how the several leaf units 9 to 12 inclusive are connected by the oppositely arranged tabs l4 and I6 that have been described. The construction appears quite clear from the drawings and may be characterized as involving the employment of the rightwardly extending tabs I4 for the leaf units 9 and II and the leftwardly extending tab members l6 for the leaf units I0 and I2,- each tab having adhesive of a heat responsive nature to be rendered sticky, applied to its underside and such tab being adhered to the upper side therefore of the leaf member just beneath the same, said leaf member being a part of an associated or adjacent leaf unit so to speak. It may be noted that the tabs l6 as to a vertical arrangement are disposed at points opposite the portions intermediate the tabs 14, as will be apparent by reference to Figure l of the drawings wherein the tabs l'6 are shown in dotted lines and the tabs I4 in full lines.

Since the tab arrangements of the tabs M are the same on all of the lines 2-2 of Figure 1 the construction shown in Figure 2 applies to these lines of section. In similar manner the section of Figure '3 applies to the various sections points and lines 3-3 of Figure 1 having to do with the reversely extending tabs l6 structure.

Reference is now made to the construction by way of modification as illustrated in Figures '7 to 11 of my drawings. In this modification the leaf units comprising the folded leaf pages are interleaved together in the same manner as in reference to the construction in Figures 1 to 6 inclusive, 1. e., they are folded on substantially the same hinge line with one hinge portion inside the next hinge. portion of the adjacent leaf unit. In this modification however it is notable that the tabs I! for connecting the various leaf units together are struck out from the associated superposed leaf members of each leaf unit at the same side of the hinge or fold line I8.

The arrangement of the tabs 1''! will be observed more clearly by reference to Figure 8 of the drawings and also to Figure '7 which shows how the tabs IT on say the topmost of the leaf 3 units 19 are cut from the left hand leaf of said unit at the left side of the hinge line l8 previously referred to. The tabs ll of all of the other and lower leaf units 20, 2| and 22 are similarly cut from the left leaves of the said units and in the same direction as the topmost tabs ll. However it is notable that the tabs of the leaf unit 20 which is below the leaf unit [9 are preferably cut from the unit 20 at its left hand leaf portion at points intermediate the location of the tabs ll of the uppermost leaf unit l9. In other Words there is a sort of staggering arrangement of the tabs H as regards those in a superposed leaf unit in relation to the leaf unit next beneath and this staggering continues throughout and is illustrated or intended to be illustrated in the drawings in that the tabs [7 of the units 20 and 22 are staggered in relation to the tabs I! of the leaf units just above.

The modification of my invention illustrates the flexibility with which I may utilize the peculiar tab connections employed between the leaf units described.

In all instances of use of the tabs that connect the various leaf members of my book whenever the book is closed the tabs will occupy the cutout portion of the next leaf member from which they are struck as distinguished from the leaf member to which the tabs are adhesively applied.

In the modification of Figures 7 to 11 inclusive the adhesive is designated 23 as it is applied to the side of the tab members which are to be connected to adjacent leaves of the book. In the two modifications of my invention as described also the lowermost leaf members may be adhesively connected to the cover or bound thereto in any suitable manner according to bookbinding practice utilizing cloth lining features.

In using a book with the leaves bound therein according to my invention the stress on the bounded portions of the leaves or sheet of the book takes place when the angle of leverage is substantially zero; Therefore this stress is practically negligible and there is no tendency for the leaves to be torn out or become displaced from their proper positions in assembled condition in the sheet section of the book.

When a series of leaf units such as I have described in conjunction with the modifications of my invention, are assembled or packed to provide the sheet or leaf body of a book it will be apparent that by subjecting the assembly of such leaf units to pressure and suificient heat to render the adhesive applied to the tabs tacky or adherent, the whole assembly will be united together by a single operation practically speaking. It is obvious that a great economy may be obtained in the manufacture and production of books by the employment of my construction of connecting means between the leaves and the method of assembling the same along the lines above referred to.

As previously intimated the punching of the tabs and applying of the adhesive thereto may be accomplished automatically if desired and the folding, stacking, compressing and application of heat may be performed so expeditiously as to enable the books of my invention to be made at practically as low an expense as ordinary scratch pads or memo pads are made today. There is no bulking of the books unevenly to interfere with the proper trimming.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

'1. A leaf section for a book including a plurality of U-folded leaf units, each composed of two leaves connected at a fold or hinge line, one leaf of each unit having a series of tabs cut therefrom hinging on the leaf at the hinge line and adhesively attached flat to the body of an adjacent uncut leaf of a second unit adjacent to the hinge line and at the surface portions thereof, opposite "the spaces from which the tabs are cut from the leaf first mentioned, said leaf units being assembled by interleaving one U-folded unit within the other, the tabs connecting leaves of a first and second unit of the leaf section being located in vertical planes staggered with respect to the vertical planes of like tabs connecting second and third leaf units of the section.

2. A leaf section as claimed in claim 1 in which the tabs connecting the adjacent leaves of the several leaf units extend in the same direction from the hinge or fold lines of their respective units.
